TOXICOLOGICAL EVALUATION OF CERTAIN
FOOD ADDITIVES
WHO FOOD ADDITIVES SERIES 16
Geneva, 23 March - 1 April 1981
The International Programme on Chemical Safety (IPCS),
established in 1980, is a joint venture of the United Nations
Environment Programme (UNEP), the International Labour Organisation
(ILO), and the World Health Organization (WHO). The overall objectives
of the IPCS are to establish the scientific basis for assessment of
the risk to human health and the environment from exposure to
chemicals, through international peer-review processes, as a
prerequisite for the assistance in strengthening national capacities
for the sound management of chemicals.
The Inter-Organization Programme for the Sound Management of
Chemicals (IOMC) was established in 1995 by UNEP, ILO, the Food and
Agriculture Organization of the United Nations, WHO, the United
Nations Industrial Development Organization and the Organisation for
Economic Co-operation and Development (Participating Organizations),
following recommendations made by the 1992 UN Conference on
Environment and Development to strengthen cooperation and increase
coordination of the policies and activities pursued by the
Participating Organizations, jointly or separately, to achieve the
sound management of chemicals in relation to human health and the
environment.

Notes
1. N, new specifications prepared; O, specifications not prepared;
R, existing specifications revised; S, specifications exist,
revision not considered; T, the existing, new or revised
specifications are tentative and comments are invited.
2. Temporary acceptance.
3. Group ADI for riboflavin and riboflavin-5'-phosphate expressed as
riboflavin.
4. On the available evidence, this substance should not be used as a
food additive.
5. Hydrogen cyanide and its salts should not be used as such as food
additives.
6. Group ADI for other glutamate, calculated and expressed as
glutamic acid.
7. The statement "ADI not specified" means that, on the basis of the
available data (chemical, biochemical, toxicological, and other),
the total daily intake of the substance, arising from its use at
the levels necessary to achieve the desired effect and from its
acceptable background in food, does not, in the opinion of the
Committee, represent a hazard to health. For this reason, and for
the reasons stated in the individual evaluations, the
establishment of an acceptable daily intake (ADI) is not deemed
necessary.
8. Group ADI for pectins and amidated pectins, singly or in
combination.
9. This solvent should not be used in food processing.
10. Residues of toluene occurring in foods when this solvent is used
in accordance with good manufacturing practice would not pose any
toxicological problems.
11. Group ADI for propylene glycol esters of fatty acids calculated
and expressed as propylene glycol.
12. Group ADI. The Committee concluded that the ADI for ascorbic acid
and its potassium and sodium salts should be changed from
0-15 mg/kg of body weight to "not specified", and that the
calcium salt should be included in this ADI.
13. The specifications were revised to include a limit for
5-hydroxymethylfurfural of 0.05%.
14. The ADI is for polydextrose A and polydextrose N, singly or in
combination.
15. Group ADI for other carbonates and bicarbonates established in
